NORRIS GOODRIGH, OF BQTTLEOBEEK, MICHIGAN, ASSIGNOR TO SANITARIUM EQUIPMENT COMPANY, OF BATTLE CREEK, MICHIGAN THERAPEUTIC LAMP Application filed February 6, 1929. Serial No. 337,814.

The main object of this invention is to provide a therapeutic lamp adapted to produce ultra-Violet and also infra-red rays;

A further object is to provide a lamp hav-- ment of my invention is illustrated in theaccompanying drawing, in which:

Fig. 1 is a perspective view of my improved therapeutic lamp.

Fig. 2 is a diagrammatic view illustrating the connections for the parts, the lamp being shown in one adjustment.

Fig. 3 is a diagrammatic view with the lamp shown in another adjustment.

In the embodiment illustrated, the reflector 1 is tiltingly mounted upon a standard 2. The details of this mounting are not, part of this invention. x The reflector 1 is provided with a segmental guard 3 disposed across its lower end and adjacent its front edge to retain any dbris that may fall from the electrodes.

The reflector is provided with a ventilating opening 4 on its upper side.

I provide an arc lamp, the electrodes 5 of which project through openings 6 in the sides of the'reflector so that-the arc is central of the lamp. These electrodes are mounted for manual adjustment, the adjusting means being indicated at 7, the details however not being illustrated as they form no 40 part of this invention.

I also provide a resistance coil 8 which" is wound upon a suitable core and is connected in series with the electrodes. This resistance coil is of suchcharacter that it becomes heated to a dull red, producing the Having thus Mdy improved lamp is well adapted 'for pro ucing infra-red rays as well as rays resulting from the arc lamp at the same time the lamp is very economical to produce and easily manipulated.

I have illustrated and described my im; provements in an embodiment which I have found very practical. I have not attempted to illustrate and describe other embodiments or'ad'aptations as it is believed that this disclosure will enable those skilled in-the art to embody or adapt my improvements as may be desired.

described "my invention, what I claim as new and desire to secure by Let- 5 ters Patent, is: i

1. In a therapeutic lamp, the combination of a reflector provided with aventilating opening in its upper side located centrally with its upper edge substantiallyspaced from the edge of the reflector, a pair of electrodes diisiposed in cooperative relation .within said re ector centrally below said ventilating opening,-- and a segmental guard disposed transverselyacross the bottom of the vreflector in a plane perpendicular to the axis of the reflector, in advance of a similar plane passing through the electrodes.

' .2. In a therapeutic lamp, the combination 7 of a reflector, an arclamp operativelyv assoo ciated withsaid reflector and comprising electrodes projecting into the reflector, and a transversely disposed segmental guard ex ten ing across the bottom of the reflector in a plane perpendicular to the axis of the reflector, in advance of a similar plane passing through the electrodes.

In witness whereof I have hereunto set-my infra-red rays. The resistance coil is ar- 7 ranged in the upper part of the lamp above the electrodes. If it is desired to use the infra-ray unit or element exclusively, the elec- 60 trodes may be" shorted as indicated in Fig. 3.
